JO N R. snow, or CHARLOTTE, MICHIGAN ICE SCORING MACHINE Applicationfiled December 26, 1929. Serial No. 416,535.

The main objects of this invention are:

First, to provide an ice scoring machine which is automatic inoperation, oflarge capacity, and at the same time comparatively simplein structure.

Second, to provide an ice scoring machine in which the driving means forthe elevator is automatically controlled by the deliveryof the work tothe elevator.

Third, to provide in an ice scoring machine an improved elevator driveand control means.

Fourth, to provide in an ice scoring machine an improved safety meanswhereby the machine is automatically stopped in the event of failure ofthe operating means.

7 Objects pertaining to details and economies of my invention willdefinitely appear from the description to follow. The invention isdefined in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:.

Fig. 1 is a side elevation of my improved ice scoring machine.

Fig. 2 is a transverse section on line 22 of Fig. 1.

F Fig. 3 is a transverse section online 3-3 of In the embodimentillustrated the frame 1 is built up of structural steel and is of asuitable character to support the various parts, but as the details of.this frame are not made the subject matter of this application they arenot described herein except as the other parts are related thereto.

The elevator guide rods 2 are mounted in the frame in an inclinedposition, that is, they are inclined relative to a vertical plane. Theentire frame structure in the embodiment illustrated is supported ininclined position by varying the length of the legs 3, 4 and 5. Thispermits the other parts of the frame to be easily assembled.

The elevator 6 is slidably mounted on these guide rods, the platformproper of the elevator beingmounted on the slides-7 carried by the rodsso that the elevator reciprocates' or travels in an inclined path. Theelevator 5 lifting cables 8 are provided with winding drums 9 carried bya sleeve 10 on the elevator driving shaft 11.

A clutch designated generally by the numeral 12 is provided forconnecting the sleeve to the shaft, and the bell crank 13 is providedfor the shifting of this clutch. This lever is connected by a link 14 toan arm 15 on the rockshaft 16 disposed at the rear end of the machine.This rockshaft 16 has anarm 17 projecting forwardly to support theclutch actuating member 18 which is positioned to act as a bumper forthe blocks of ice as they are delivered on to the elevator. The upperend of this actuating member is supported by a link 19.

With this arrangement the work, or blocks of ice, sliding on to theinclined elevator platform engages the clutch actuating member-18 whichactuates the rockshaft and, through the connection described, engagesthe clutch, thereby starting the winding drums to lift the elevator. i

The work is delivered from the elevator on an inclined chute 20 having atrip 21 associated therewith to be engaged by the work discharged uponthe chute by the elevator. This chute is disposed so that when theinclined platform of the elevator comes'into alinement therewith thework slides upon the chute and, engaging the trip 21, actuates therockshaft 16. The trip is connected to an arm 22 on the rockshaft bymeans of the link 23. f

This actuation of the rockshaft releases the clutch 12 allowing theelevator to fall or return to its initial or receiving position. Theupper end of the actuating member 18 terminates adjacent the plane ofthe chute .20 so thatthe clutch is-held in engagement until the work isdischarged upon the chute.

As the work is lifted by the elevator it is acted upon by the saws 24mounted in suitably spaced relation upon the shafts 25 disposed at eachside of the path of the elevator. These saws are arranged in a planebelow the discharging position of the elevator.

The work is delivered to the elevator by thev feed chute 26 whichisdisposed in an inclined position so that the work arranged thereonslides down the same and on to the elevator platform. As the worktravels along this feed chute it is acted upon by the saws 27 mounted onthe vertically disposed shafts 28 at each side of the feed chute. Theshafts 28 are provided with beveled gears 29 at their 7 upper ends whilethe shafts 25 are provided with beveled gears 30.

The transmission shaft 31 is disposed transversely of the machine andprovided with beveled gears 32 which mesh with both the saw shaft gears29 and 30.

One of the saw shafts 25 is provided with an extension 33 the front endof which is supported in a bearing 3 and connected bythe universal joint35 to the driving shaft 36 geare'd'to the motor 37. The shaft 11 isprovided with the beveled gear 38 at its forward end meshing withthebeveled gear 39 on the transmission shaft 40, which is connected to thesaw shaft having the extension 33 by worm gearing arranged within thehousing 41.

To prevent breakage in theevent of failure of operation of the clutchcontrol mechanism, such as might result from clogging, I provide asafety switch control mechanism for the motor designated generally bythe numeral 42 and provided with a trip lever 43 projecting into thepath of the elevator to be engaged thereby in the event of an abnormaltravel or stroke of the elevator. The electrical connections for thecontrol member to the motor are not illustrated as these will be readilyunderstood.

My improved ice scoring machine is of large capacity, is automatic inoperation, it only being necessary to deliver the work to the feedchute, and at the same time is comparatively simple and economical instructure.

-I have not attempted to illustrate or describe certain embodiments ormodifications which I contemplate as it is believed that this disclosurewill enable those skilled in the art to embody or adapt my improvementsas may be desired.
